Showing Azure Resources in VSCode is very slow

There is some problem with showing Azure Resources in VSCode such that it is very slow. The progress indicator at the top of the Resources panel continues animating basically forever and never finishes loading. The Pay-As-You-Go node is shown, and if I click on a sub-node, like Azure Cosmos DB, then the sub-resources are shown, but this can sometimes take 30 seconds or more to show.

I don't know if it is related, but I did notice in the VSCode Output panel for Microsoft Authentication, that authentication log messages repeat continuously. By showing the Debug log level I can see that this happens because of refreshing the token. I don't know if this is intended, but since it happens ever second or so it seems excessive. Below is a example of the logs I'm seeing:

The reason I think the Resources being slow may be related to authentication is because if I sign out of Microsoft and then sign back in then the Resources view quickly loads completely (without the progress animation continuing forever), and when I expand the sub-nodes the expand almost instantly without delayed loading. Similarly, the forever-repeating authentication log messages have stopped. The problem is that this problem returns later. I don't know what causes it to start happening again, it just does after a while.

If there is anything more I can do to help diagnose this, please let me know.

Start by reproducing the slow Azure Resources view and compare behavior before and after signing out and back in. Inspect the Resources panel behavior alongside the Microsoft Authentication output, especially the repeated token-refresh messages. Done means resource and sub-resource loading completes normally without persistent progress or excessive repeated authentication refreshes.
